VAPORIZING-TUBE.

SPECIFICATION forming part of Letters Patent No. 632,495, dated September 5, 1899.

Application filed January 16, 1899. Serial No. 702,218. (No model.)

To all whom it may concern/.-

Be it known that I, ARTHUR KITSON, a subject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Vaporizing- Tubes, of which the following is a specification.-

My invention relates to vapor-burning apparatus, and is specifically designed to produce an improved form of vaporizing-tube.

One difficulty encountered in the use of vapor-burning apparatus in which the heat of the burner vaporizes the oil in the vaporizingtube or other chamber is that when the poor grades of oil are used a considerable quantit-y of carbon or other solid matter is deposited in the vaporizing-tube, and getting into the discharge-orifice interferes with the discharge of the vapor and the even operation of the lamp. My present invention presents one method of overcoming this difficulty; and it consists in bending the vaporizing-tube so that the end containing the discharge-opening will be bent to one side of but remain parallel to the main body of the tube and then so arranging the tube in the lamp structure that the bent portion of the tube containing the discharge-opening will be above the level of the main portion of the tube.

The preferred form of apparatus embodying my invention is disclosed in the accompanying sheet of drawings, in which- Figure 1 is a central section of the operative portion of the vapor-burning lamp with my improved vaporizing-tube in position. Fig. 2 is a detail view showing the end of the vaporizing-tube and a latch for holding it in position.

Throughout the drawings like reference-figures refer to like parts.

The parts of the vapor-burning lamp shown are the chimney 1, the reflector 2, mixingtube 3, and the burners at, preferably having the incandescent mantles 5 over them. The lamp is suspended from the hanging-rod 6 and has the heat-shield 7. The mixing-tube has an enlarged month 8, in which may be located the injector-cone 9, if desired. cone may be adjustably mounted by means This upper end are connected, the ring 10 being adjustable on the mouth of the mixing-tube by means of the set-screw 11. The particular.construction of adjustable cone 9, however, is not herein claimed, as the same is covered by my pending application, Serial No. 702,217, filed January 16, 1899.

The vaporizing-tube has a main body 12 and the bent portion 13, parallel to the main body, but on a higher level when the tube is in position, as shown in Fig. 1. The discharge-opening for the jet 14 is in the lower Wall of the bent portion, and one or more wire-gauzes 15 are arranged in the tube in front of the discharge-opening.

The vaporizing-tube extends across the chimney 1 and through openings 16 and 17 in the walls thereof, said openings being so located as to render the main body 12 of the vaporizing-tube horizontal when it extends through the opening 17, while the bent portion of the tube extends through the opening 16.

On the end of the vaporizing tube farthest from the discharge-opening is the notched feather 18, which passes through a slot 19 in the chimney-wall, adjacent to the opening 16 therein, and into the notch in said feather 18 fits the spring-latch 20, which holds the vaporizing-tube in position. (See Fig. 2.)

The method of operating my invention is as follows: Oil being admitted to the vaporizing-tube is vaporized in the lower level 12, and any carbon orother solid matter in said oil is deposited in said section. The vapor passes on into the bent portion 13 and out through the discharge-opening 14:. No carbon or other solid matter getting into the portion 13 on a higher level, the discharge-opening is left free from clogging.

The injector-cone being properly adjusted by means of the collar 10 and set-screw 11, the necessity for having the discharge-opening 14 nicely centered with reference to the mixingtube 3 is not so great as where no adjustable cone is used, and a sufficiently accurate adjustment can be obtained by the apparatus shown, in which the tube is held from sliding by the latch 20 engaging the other end of the vaporizing-tube.

of the ring 10, to which extensions from its Of course the varying degrees of expansion of the tube when the lamp is under the different temperatures to which it is subjected will cause the discharge-opening 14 to vary its position slightly, (the tube being held at the other end by the latch 20;) bnt,'as before stated, the use of the cone 9 renders this variation possible Without seriouslyinterfering with the operation of the lamp.

It is evident that various changes could be made in the details of the apparatus disclosed without departing from the spirit and scope of my invention, so long as the vaporizingtube operated on the principle described is employed. The bend between the two sections of the tube might be differently located from that shown and might be of different shape, or the tube might be held in position by other forms of apparatus, &c.; but all these I consider mere changes in form and not in the principle of my invention.

Having therefore described my invention, what I claim as new, and desire to protectby Letters Patent, is

1. In a vapor-burning apparatus a continuous vaporizing-tube having its end containing the discharge-opening bent to one side of but parallel to the main body of the tube, in combination with the vapor-burner, and the supporting-frame, in which the vaporizingtube is held above the vapor-burner with its main body horizontal and with the bent portion above the level of the main body, the

discharge-opening for the vaporizing-tube being in theunder side of the discharge end, substantially as described.

2. In a vapor-burning apparatus the combination of the vapor-burner, the mixing-tube, the chimney above the burner, the vaporiz ing-tube extending through and across the chimney, and having a discharge-opening opposite the month of the mixing-tube, the adjustable cone located before said dischargeopening, the notched feather on the other end of the tube, which feather engages a slot in the chimney-wall, and the latch mounted on the chimney and engaging said notch, substantially as described.

3. In a vapor-burning apparatus the combination of the vapor-burner, the mixing-tube, the chimney above the burner, the vaporizing-tube extending through and across the chimney and having a discharge-opening opposite the mouth of the mixing-tube, the ad justable cone located before said dischargeopening, and the spring-catch which is mounted on the chimney and engages the other end of the vaporizing-tube to hold it in place, substantially as described.

Signed by me at New York, N. Y., this 7th day of January, 1899.

ARTHUR KITSON.
